I don't mean to turn this into a fanboy console war thread, but honestly the PS3 has a lot going for it.

MAG is an excellent new game coming out featuring 128v128 matches, a PS3 exclusive and one that I'm thoroughly enjoying the beta for. Infamous, Prototype, heck even Disgaea 3 if you like tactical turn-based strategy.

Also, the Playstation Network has no monthly fee and none of the Nazis that spy on voice communications looking for swear words.
